This February the US Navy placed the nuclear-powered attack submarine USS Jimmy Carter (SSN-23) in commission. Jimmy Carter is the latest and last of the Seawolf-class attack submarines.

During construction, Jimmy Carter received extensive modifications in order to conduct 'special missions',
meaning classified hush-hush operations that we'll never hear about. The kind of modifications that were done to the boat is also classified, but as is often the case, some enterprising photographer managed to get a picture of the boat.
